Answer:

The volume of the gas is 0.015 m^3.

Explanation:

mass, m = 32 g

Temperature, T = 45 °C = 45 + 273 = 318 K

Pressure, P = 728 mm of hg = 0.728 x 13.6 x 1000 x 9.8 = 97027.84 Pa

Atomic mass = 4 x 12 + 10 x 1 = 58 g

Use the ideal gas equation

Let the volume is V.

P V = n R T

97027.8 \times V = \frac{32}{58}\times 8.31 \times 318 \\\\V = 0.015 m^3

Explanation:

The volume of the gas occupied can be calculated by using the ideal gas equation:

PV=nRT

where,

P=pressure of the gas in atm

V=volume of the gas in L.

n=number of moles of the gas

R=0.0821L.atm.mol-1.K-1

T=absolute temperature

To get the volume of the gas, follow the below steps:

1) Calculate the number of moles of gas:

Number of moles of butane=mass of butane given/its molecular mass

=32g/58.0g/mol\\=0.55mol

2) Convert temperature into kelvin scale:

T=(45+273)K=318K

3)Convert pressure into atm:

760 mm Hg =1 atm

then,

728 mm Hg=

728 mm Hg x 1 atm /760 mm Hg

=0.957 atm

Substitute all these values in the ideal gas equation to get the volume:

V=\frac{nRT}{P} \\V=0.55mol x 0.0821 L.atm.mol-1.K-1 x 318K / 0.957 atm\\V=15.0L

Answer:

The volume of butane gas is 15.0 L

Determine % yield if a student obtains 45 g of product in an experiment and the theoretical amount is determined to be 50 g. *
ycow [4]

Answer:

90%

Explanation:

Percentage yield = ?

Theoretical yield = 50g

Actual yield = 45g

To calculate the percentage yield of a compound, we'll have to use the formula of percentage yield which is the ratio between the actual yield to theoretical multiplied by 100

Percentage yield = (actual yield / theoretical yield) × 100

Percentage yield = (45 / 50) × 100

Percentage yield = 0.9 × 100

Percentage yield = 90%

The percentage yield of the substance is 90%

What is the mole ratio of D to A in the generic chemical reaction 3A + B C + 4D
ehidna [41]

Answer:- Mole ratio of D to A is 4:3.

Explanations:- Mole ratio for a chemical reaction is the ratio of the coefficients.

The given generic chemical reaction is:

3A+B\rightarrow C+4D

The numbers written in front of each chemical species in the chemical reaction are their moles. For the given generic chemical reaction the coefficient of A is 3 and that of B is 1. So, the mole ratio of A to B is 3:1.

Similarly if we want to write the mole ratio of C to D then it is 1:4.

We are asked to write the mole ratio of D to A. So, like the other ratios, the mole ratio of D to A is 4:3 as the coefficient of D is 4 and A is 3.
